Conclusions 1. With a CRP density decrease of 7% the greatest thermal strain value increases by 32% (during heating at a specific rate). Shrinkage arising in the material during cooling also depends on material density, and a specific gravity difference of 7% increases shrinkage by a factor of 4.5. 2. Marked anisotropy is demonstrated in thermal strain of CRP based on phenol-furfurol resin: strain of specimens cut along the warp is positive, but along the weft it has a variable sign, and amplitude of their relative values is three times greater than for strain along the warp. 3. The effect of atmosphere composition on thermal strain of heat-reflecting CRP was established: strain values are greater in an oxidizing atmosphere and they appear at a higher temperature than in a neutral atmosphere; there is an opposite relationship for the least values of thermal strain as a function of heating rate.
